Alone, cold, sad, hurt... This man was a wreck from the start. He had started smoking marijuana a week prior to this tragic event, that's when his life began to slope downward. Soon he was wasting all of his time and money on Mary Jane, the allure of his dancing wallpaper and the amount of pepperonis on his pizza was too great to resist.
Then his wife left him.
That was the blow that cracked his fragile psyche, I suppose. Cast into a brutal pit of despair he tried to claw his way out - but it was too late.
Swallowed (lol) by a mixture of sadness, rage, and high this was easily foreseen.
His brother found him two days later.
Oh, and there is an Easter egg. I'm not sure you'll be able to find it easily though.
